![]() The metal is passed between two rollers which rotate at the same speed but it is in the opposite direction. The rotation of that two rolls is made in two different directions. In this type of mill, both rollers are adjustable. They are further categorized into the following types: There are five rolling mills which are commonly used for rolling metals: This process offers a good surface finish. In this process, the force requirement is much more than the hot working process to pass the metal from the rollers. The cold rolling process is done below the recrystallization temperature of the metal. In the hot working process, the metal changes its grain structure because of the heat, now there were a new set of strain-free grains in the metal and this process needs less amount of force which correspondingly reduces the quality of the surface finish, of that metal. The metal is heated above the recrystallization temperature. When the metal is properly heated then the metal should be passed between one or more rolling mills to gain the proper desirable shape. There are certain types of the rolling process, whereas, in the hot rolling process, the metal is heated up to its desirable temperature. ![]() The rolling processes are mainly focused on the increasing length and the decreasing thickness without changing the width of the workpiece. Using this process, we can reduce the thickness of the metal workpiece. This process is mainly focused on the cross-section of the ingot or the metal which is forming. The rolling process is a metal-forming process, in which a stock of the material is passed between one or more pairs of rollers to reduce and maintain the uniform thickness. Rolling is a process that is widely used and has very high production rate. If this is done at room temperature then it is termed as Cold rolled. If the strip is rolled after heating the strip above the re-crystallization temperature then it is termed as Hot rolled. Due to this a uniform thickness is maintained. Rolling is defined as a process to form metals where the metal strip is pressed by two or multiple rollers. This process has various advantages and disadvantages which we will discuss in detail. This process is generally used to make flat sheets, bars & other shapes. ![]() It is done by passing a strip of metal between the rollers. Rolling is the deformation process of a metal that is widely used in the metal forming process. What are the advantages of Rolling process?. ![]()
